EMIL HUBER, OF DETROIT, MICHIGAN.

CLUTCH.

Specification of Letters Patent.

Patented May 7, 1907.

Application filed October 16, 1905. Serial No. 282,920.

To alZ whom it may concern:

Be it known that I, 'EMIL HUBER, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Clutches; and I declare thefollowing to be a full, clear, and exact description of the same, suchas will enable others skilled in the art to which it pertains to makeand use the same, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to clutches and has for its object an improvedclutch and one that causes no end thrust upon the engine.

In the drawings :-Figure 1, is a longitudinal section of a clutchembodying my invention and parts adjacent thereto and cooperatingtherewith. Fig. 2, shows the lever employed to actuate the clutch. Fig.3, is an elevation of a forked lever or actuator.

1, is a driving shaft, as for instance, the main shaft of a gas engine.

2, is a fly-wheel rigidly secured upon the shaft 1.

A, is a flange upon the end of the shaft 1.

A is a short shaft having a flange A at one end. The shaft A is securedto the shaft 1, axially in line therewith by bolts 3 extending throu hthe flanges A and A and through the web of the fly-wheel. The flange ofthe fly-wheel is formed to constitute one portion of a conical clutch asindicated at 5 5, is a clutch-head adapted at its periphery to engagewith the conical surface upon the flange of the fly-wheel 2, by motionin the direction of the axis of said fly-wheel.

4, is a sleeve adapted to turn upon the shaft A and forming an integralpart of the clutch 5.

15, is a nut upon the end of the shaft A 13, is a helical compressionspring surrounding the shaft A and pressing at one end against theclutch 5 and at the other end against the roller thrust bearing A whichis against, and held by, the nut 15.

4, is a sleeve inclosing the spring 13 and having at one end a flange 4which is rigidly bolted to the clutch-head 5, and at the other end aflange 4 which is rigidly bolted to a flange 4 upon the transmissionshaft A.

A, is a thrust bearing surrounding the shaft A between the flange A andthe sleeve 4.

7, is a ring sleeved upon the sleeve 41, provided with an outwardlyextending flange, and adapted to bear against the thrust bearin A.

is a collar upon the sleeve 4, in the construction shown forming a partof said sleeve.

8, is a ring upon the sleeve 4 adapted to slide longitudinally thereof.

6, 6, are rods or pins secured to the ring 8, by a forced fit in theconstruction shown, extending through apertures in the flange 4 and theclutch-head 5 and bearing at their inner ends against the side of theflange on the sleeve 4 The actuator of the clutch engages between theloose ring 8 and the collar 9 and consists of a pair of forked leverheads 10 and 1 1, each lever head is forked with two branches 10 and 10and the branches terminate with rollers 11 and 11 9, said forks 'arepivoted to any fixed support and are provided with lever arms 10 and 10,which are connected by a toggle 12, said toggle is provided with handlesby means of which the levers just mentioned may be actuated to press thering 8 toward the fly-wheel 2.

The operation of the above described device is as follows :N ormally thespring 13 presses the clutch 5 against, and holds it in engagement with,the conical surface upon the fly-wheel. The pressure of the spring is inone direction against the thrust bearing A upon the shaft A and in theother direction an equal amount upon the clutch head 5, and through thatto the fly-wheel rigidly connected to the shaft A so that the two forcesof the spring are communicated to the same part and balance each otherwithout being conveyed to the engine. When the clutchhead 5 is inengagement with the wheel 2, the transmission shaft A is connected tothe driving shaft 1 through the sleeve 4, and said clutch head. When itis desired to disengage the clutch-head, the forked lever heads 10 and11 are actuated to move the ring 8 toward the fly-wheel 2, pressing thesleeve 7 inward against the thrust bearing A by means of the pins 6, 6,and moving the sleeve 4 and shaft A longitudinally by means of thepressure of said lever-head against the collar 9, thus drawing theclutch 5 out of engagement with the fly-wheel 2.

When the actuators are released the spring 1 13 causes the clutch 'torengage. It will be observed that both of the bearings A and A areinclosed and protected from dust and irt.

What I claim is 1. The combination of a driving shaft 1, A a drivenshaft 4, A", a clutch member on each of said shafts adapted to engage tobind said shafts together, a spring 13 interposed. between said shaftsand tending to force them in opposite directions to engage said clutchmembers, and. an actuator upon one of said shafts acting against theother of said shafts to press said shafts apart to disengage theclutches.

2. The combination of a driving shaft 1, A a driven shaft 4, A having asleeve 4 surrounding a part of the driving shaft, a spring surroundingsaid driving shaft within the sleeve 4, a thrust bearing within saidsleeve interposed between said spring and the driving shaft, said springacting at the other end against the driven shaft, a clutch member 5 onthe driven shaft, a corresponding clutch.

member upon the driving shaft, a thrust bearing inclosed by said clutchmember, an actuating member extending through one of said clutch membersadapted to act upon said thrust bearing, and. means for operating saidactuating member, for the purpose described.

3. The combination of a driving shaft 1, A a driven shaft 4, A having asleeve 4 surrounding a part of the driving shaft, a spring a surroundingsaid driving shaft Within the sleeve 4, said spring acting at the otherend against the driven shaft, a clutch member 5 on the driven shaft, acorresponding clutch member upon the driving shaft, a thrust bearinginclosed by said clutch members, an actuating member extending throughone of said clutch members adapted to act upon said thrust bearing, andmeans for operating said actuating member, for the purpose described.

In testimony whereof, I, sign this specification in the presence of twowitnesses.

EMIL HUBER.
